CONCRETE SCOW.

vSpecieati'on of Application led September coine to my' attention'as the result of careful investigation, I have found to have been a failure, for 'the reason 'that the netV displacement available is relatively minute for a iven size 'sco'w, diie largely tothe fact, that in all types heretofore pro ose d, heavy concrete Walls and bulk hea s hadto be ern 'ployed in order to obtain the requisite strength to withstand the stresses and. strains niet with in practice. I have particularly in ininda scow which is construct ed of a concrete hull and deckof the saine general design as that 'disclosed in thedrawin'gs of my application, infwhicli the reinforce element consists of L-irons, and as the result, the weight of the finished' seow is so great 'tliatjt displaces so iniichwater as to bring the 'water li'ne very close to the deck and leave a comparatively small net displacementto take care of -the load.

My invention, therefore, primarily has' for its object to provide a sc ow constructed of reinforced concrete in such a manner that .35

the minimum weight may be combined with the maximum strength to obtain a maxi-- mum displacement available for the load,

and thus'for a given sizescow' increase the form of open mesh work suc I t ple as is known in the trade vas Clinton car'g'p earrvi'iig capacity `thereof over the capacity of those scows constructed. along the lines of those heretofore known inthe In its general nature'the present invention comprises a seow, the hull and deck of which is an integral structure com o'sed of a.

forexamwire, wl1ich form is embedded in concrete;` the interior ofthe hull is divided bv a central lon 'tudinal web or bulk head df concrete rein orced by rods po located4 an'd designed `as 'to take uptlie strains and :jstresses along the bulk head;' the interior of the hull on each side of the central longitudinal bulk head being further divided by webs to form open bulk heads or Letters Patent Patented Feb. 27,1912. c, 1911. serial Nq. 647,867.)

., iir walls, which are constructed of concrete embedding truss rods that take up the transverse and "longitudinal strains; the vinterior vof the hull -is also provided with longitudinal and' transverse sills or beams running along the bottom and underside of the deck formed, these beams or sills being specially reinforced by rods so designed 'as to take care of the strains and stresses occurring: 4in the sills when the seow is in' use, and where the beams or sills cross the lower and upper ones areconnected by vertical posts .that arejalso. reinforced by rods and from 4which the longitudinal and transversebiil-k head webs radiate.

method of reinforcing the concrete beams, posts and-bulk head webs whereby light weight. in these 'parts maybe obtained with 'ample strength to sustain 'the Astrains and stresses met with in practice.

The invention furthermore includes those uoveldetails of construction, combination vand arrangement of parts, all of which will -'be first fully described' and then be specifically pointed out in the appended claims, `and illustrated in the accompanying drawings, in which: Figure liis a top plan view and-part hori- .zontal section of the invention. Fig. 2 is an Figa- 1. Fig. 3 is a horizontal section'on the line'3--3 of Fig. 2. Fig. 4 is an enlarged cross section'on the'line 4-4 of Fig. .1. Fig. .5 is a detail perspective view of a portion-0f the invention. Fig. G is"a longitudinal section of one end of the scow. Fig. 7 is a plan -view of a 4portion of the Clinton mesh used to 'make up the form. ofthe sco'w, that Vand deck walls.

Referring now to the accompanving drawings Ain which like numerals and 'letters of reference indicate like parts'in'all of the figures, 1 designates the hull and-Q 'the deck, which parts'are constructed of concrete 3, embedding a. ffor`rn'4f of mesh (Clinton wire or the like, .see Fig. 7 the deck being provided with the usual fence 5 constructed of mesh embedded .in concrete.

Within the hull. on the bottom thereof, is

a set of longitudinal and a setof transverse beams or sills .6. each being formed of concrete, reinforced by straightrods 7 and'by bent rods" 8,- t-he latter extending between enlarged cross'section on the line 2`2 ofv is embedded in the concrete to form the hull structure, to which they are integrally'.

The invention also resides in the special rio adjacent transverse beams and for a partl of their length, lie in the plane containing the i-'ods 7. The rods 8 include inclined portions 9 that terminate in hook-like ends 10,which with the rods 7 and 8 in their construction.

Where the longitudinal and transverse beams 6 cross one another, and Where the longitudinal and transverse beams 11 cross one another, the beams G and 11v are united by vertical p osts 15 (see Figo), which -posts are constructed of concrete and embed four vertical rods 16, whose ends drift into the beams 6 and 11 res ectivclv. Passing through the central portion of the posts 15,

and Vlying in the planes of the beams 6 and l1, are cross rods 17, whose ends 18 project into the beams 6 and 11 respectively and are bent to parallel the same to tlioieby'-form anchors'. Over the rods 17, and embedding the'same, Webs of concrete 19 and 20 are formed to radiate from the, posts 15, and.

thereby form open bulk heads or partitions, dividingthe hull into a plurality of chambers 21, as indicated in Fig. 1 of the drawings. The central bulk head 2G is a continuous unbroken Vweb from bow to stern,

while all chambers 21 .at a side communicate with one another. It will be seen that the portion of the rods 8 which lies in the plane of the rod 7, is preferably of greater length than the space 22 between the Webs 1D at the beams (i4 and 11, sons to aiford a strong secure bracing for the parts.

Where the webs 19 unit with the side .23 ofthe hull, a single rod 2-1- is employed in lieu of thecross rods 17, and the rod 24 is bent into a V-shape, and has its middle portion 25'embedded in the side posts 2G, while its bent ends A27-are anchored i in the respective beams 6 and 11.

I. have indicated the various reinforcing rods in the drawingsas twisted but while they have been sfo-indicated, I do not Wish to have it understood that I limit myself to the use' of twisted rods, as untwisted or straight rods mai;r be employed if desired, or some maybe twisted and some untwisted.

By making the hull and deck shell of a form of open-mesh, the cross points 28 of which (see Fig. 7 are welded together as in the Clintoninesh there will be provided a structure of great strength which' will have an inherent tendency to retain its shape so that when it is embedded in the concrete,. the resulting structure will 'be aV very firm shell By reason ofthe construction of the shell l am enabled to employ'l'ight reinforced rods in the beams,

posts and bulk headl webs', (a construction that is impossible in'other forms of concrete scows now known in the art) and thus render the use of heavy angle irons or L- irons unnecessary. 'The bow and stern 29 terminatin in bent 'over anchor ends 33,

of the'scow is also reinforced by the diag:..'.

onal rods 30, whose'lower ends are anchored at 31 in the bottom beams 6, and whose upper portions 82 are projected into the ends of the longitudinal beamsll, the portions 3Q as best indicated in Fig. V6 ofthe drawings. lfVhile the form of. the invention illustrated is the preferred one, it is obvious-that many changes'in the design and proportion of the parts of the scow and the number of chambers, etc., may be made 'without `departing from the spirit of the invention, or

the scope of the appended claims.
